How Can I Dynamically Change a NotifyIcon's Icon in .NET Using Embedded Resources?

Create and use resources in .NET

Embedding useful data into .NET programs can enhance functionality and maintainability. This article demonstrates how to create and use resources to solve a common problem: dynamically changing the NotifyIcon control's icon based on application state.

Create resources

Right-click your project in Solution Explorer and select Properties. Under the Resources tab, select the resource type for your data (for example, Icon). Select Add Resources to include new or existing resources.

Use resources

C# provides the Properties.Resources namespace to access embedded resources. In the sample code below, the paused variable switches the icon of NotifyIcon:

<code class="language-csharp">paused = !paused;
if (paused)
    notifyIcon.Icon = Properties.Resources.RedIcon;
else
    notifyIcon.Icon = Properties.Resources.GreenIcon;</code>

By creating and referencing resources, you can easily integrate dynamic data into your program without the need for external references or complex configuration.
